RESUMO
BACKGROUND: Pediatric long COVID remains incompletely understood with scant Australian data available. We aimed to assess the impacts of the 2021 Delta variant of SARS-CoV-2 outbreak on symptoms and functioning 12 weeks post-acute infection in a cohort of children and adolescents. METHODS: The parents/carers of 11,864 patients with PCR-confirmed SARS-CoV-2 were invited, via email or text message, to complete an online survey assessing symptoms and functional impairment. FINDINGS: 1731 (17.6%) responded to the survey. 203 (11.7%) reported continued symptoms and/or functional impairment which were flagged for clinical review, all others reported recovery. Of the 169 subsequently clinically reviewed, 63 had already recovered (37.3%) and 17 had exacerbation of pre-existing condition(s) (10.1%); 63 (37.3%) were diagnosed with a Post COVID Condition (PCC). Of these, 21 (12.4%) were considered to have features compatible with the United Kingdom consensus cases definition for Long COVID. INTERPRETATION: During an outbreak of SARS-CoV-2 an online questionnaire with subsequent clinical review revealed self-reported non-recovery at 12 weeks in a minority of cases, with a spectrum of features. Long COVID comprised only a subset of cases with self-reported non-recovery, and is infrequent in children and adolescents, but still comprises a likely significant burden that warrants attention. IMPACT: Our study provides the only comprehensive estimate of the frequency and spectrum of post-COVID conditions in children from Australia. The high frequency of self-reported recovery, and low frequency of Long COVID compatible illness adds to the literature from other settings. Risk factors for post-COVID conditions in children are identified and include: age >11 year, and previous medical co-morbidity.
RESUMO
OBJECTIVE: COVID-19 has led to significant morbidity and mortality globally. Post-COVID sequelae can persist beyond the acute and subacute phases of infection, often termed Post-COVID Syndrome (PCS). There is limited evidence on the appropriate rehabilitation for people with PCS. The aim of this study is to evaluate the effect on exercise capacity, symptoms, cognition, anxiety, depression, health-related quality of life (HRQoL), and fatigue, of a 4-week, twice-weekly supervised pulmonary telerehabilitation program compared to usual medical care for people with PCS with persistent respiratory symptoms. METHODS: The study will be a multi-site randomized controlled trial (RCT) with assessor blinding. Participants with confirmed previous COVID-19 infection and persistent respiratory symptoms who attend a post-COVID respiratory clinic will be randomized 1:1 to either an intervention group (IG) of 4 weeks, twice-weekly pulmonary telerehabilitation or a control group (CG) of usual medical care. Participants in the CG will be invited to cross-over into the IG after the week 4 assessment. Primary outcome: exercise capacity measured by the 1-minute sit-to-stand test. Secondary outcomes: 5 repetition sit-to-stand test; Montreal Cognitive Assessment; COVID-19 Yorkshire Rehabilitation Scale; COPD Assessment Test; 36-Item Short-Form Health Survey; Hospital Anxiety and Depression Scale; Fatigue Severity Scale; and the Kessler Psychological Distress Scale. Outcomes will be collected at baseline, after 4-weeks intervention or control period, after intervention in the cross-over group, and at 12-month follow-up. IMPACT STATEMENT: Research into effective rehabilitation programs is crucial given the substantial morbidity associated with PCS and the lack of long-term data for COVID-19 recovery. A short duration pulmonary telerehabilitation program, if effective compared to usual care, could inform practice guidelines and direct future clinical trials for the benefit of individuals with persistent respiratory symptoms post-COVID.
RESUMO
BACKGROUND AND AIMS: Alcohol use and anxiety often co-occur, causing increased severity impairment. This protocol describes a randomized controlled trial (RCT) that aims to test the efficacy and cost-effectiveness of a web-based, self-guided alcohol and anxiety-focused program, compared with a web-based brief alcohol-focused program, for young adults who drink at hazardous levels and experience anxiety. It will also test moderators and mechanisms of change underlying the intervention effects. DESIGN: This RCT will be conducted with a 1:1 parallel group. SETTING: The study will be a web-based trial in Australia. PARTICIPANTS: Individuals aged 17-30 years who drink alcohol at hazardous or greater levels and experience at least mild anxiety (n = 500) will be recruited through social media, media (TV, print) and community networks. INTERVENTION AND COMPARATOR: Participants will be randomly allocated to receive a web-based, integrated alcohol-anxiety program plus technical and motivational telephone/e-mail support (intervention) or a web-based brief alcohol-feedback program (control). MEASUREMENTS: Clinical measures will be assessed at baseline, post-intervention (2 months), 6 months (primary end-point), 12 months and 18 months. Co-primary outcomes are hazardous alcohol consumption and anxiety symptom severity. Secondary outcomes are binge-drinking frequency; alcohol-related consequences; depression symptoms; clinical diagnoses of alcohol use or anxiety disorder (at 6 months post-intervention), health-care service use, educational and employment outcomes; and quality of life. Mediators and moderators will also be assessed. Efficacy will be tested using mixed models for repeated measures within an intention-to-treat framework. The economic evaluation will analyze individual-level health and societal costs and outcomes of participants between each trial arm, while mediation models will test for mechanisms of change. COMMENTS: This will be the first trial to test whether a developmentally targeted, web-based, integrated alcohol-anxiety intervention is effective in reducing hazardous alcohol use and anxiety severity among young adults. If successful, the integrated alcohol-anxiety program will provide an accessible intervention that can be widely disseminated to improve wellbeing of young adults, at minimal cost.

BACKGROUND: Tapeworms are parasitic flatworms that independently evolved a segmented body plan, historically confounding comparisons with other animals. Anteroposterior (AP) patterning in free-living flatworms and in tapeworm larvae is associated with canonical Wnt signaling and positional control genes (PCGs) are expressed by their musculature in regionalized domains along the AP axis. Here, we extend investigations of PCG expression to the adult of the mouse bile-duct tapeworm Hymenolepis microstoma, focusing on the growth zone of the neck region and the initial establishment of segmental patterning. RESULTS: We show that the adult musculature includes new, segmental elements that first appear in the neck and that the spatial patterns of Wnt factors are consistent with expression by muscle cells. Wnt factor expression is highly regionalized and becomes AP-polarized in segments, marking them with axes in agreement with the polarity of the main body axis, while the transition between the neck and strobila is specifically demarcated by the expression domain of a Wnt11 paralog. CONCLUSION: We suggest that segmentation could originate in the muscular system and participate in patterning the AP axis through regional and polarized expression of PCGs, akin to the gene regulatory networks employed by free-living flatworms and other animals.
RESUMO
OBJECTIVE: There have been no well-controlled and well-powered comparative trials of topiramate with other pharmacotherapies for alcohol use disorder (AUD), such as naltrexone. Moreover, the literature is mixed on the effects of two polymorphisms-rs2832407 (in GRIK1) and rs1799971 (in OPRM1)-on response to topiramate and naltrexone, respectively. The authors sought to examine the comparative effectiveness of topiramate and naltrexone in improving outcomes in AUD and to examine the role of the rs2832407 and rs1799971 polymorphisms, respectively, on response to these medications. METHODS: In a 12-week, double-blind, placebo-controlled, randomized, multisite, genotype-stratified (rs2832407 and rs1799971) clinical trial comparing topiramate and naltrexone in treating AUD, 147 patients with AUD were randomly assigned to treatment with topiramate or naltrexone, stratified by genotype (rs2832407*CC and *AC/AA genotypes and rs1799971*AA and *AG/GG genotypes). The predefined primary outcome was number of heavy drinking days per week. Predefined secondary outcomes included standard drinks per drinking day per week, body mass index (BMI), craving, markers of liver injury, mood, and adverse events. RESULTS: For the number of heavy drinking days per week, there was a near-significant time-by-treatment interaction. For the number of standard drinks per drinking day per week, there was a significant time-by-treatment interaction, which favored topiramate. There were significant time-by-treatment effects, with greater reductions observed with topiramate than naltrexone for BMI, craving, and gamma-glutamyltransferase level. Withdrawal due to side effects occurred in 8% and 5% of the topiramate and naltrexone groups, respectively. Neither polymorphism showed an effect on treatment response. CONCLUSIONS: Topiramate is at least as effective and safe as the first-line medication, naltrexone, in reducing heavy alcohol consumption, and superior in reducing some clinical outcomes. Neither rs2832407 nor rs1799971 had effects on topiramate and naltrexone treatments, respectively.

OBJECTIVE: Despite the known importance of regularly monitoring progress when delivering psychological interventions, this is not mandated or seemingly even common practice on Australian inpatient psychiatric wards. Barriers for why this might be the case are described, an argument made to rise above them, and a call for research in this area is made. CONCLUSIONS: Failure to find ways to collect, analyse and be transparent with data around brief inpatient psychological interventions can diminish treatment outcomes and leaves us open to criticism as a profession.

OBJECTIVES: The aim of this study was to describe the characteristics of clients receiving home-based dietetic intervention and to evaluate the effectiveness of these interventions in improving nutritional status, functional status, and quality of life in a culturally and socioeconomically diverse client group. METHODS: Participants referred to a home-based dietetic service were recruited to this prospective cohort study. Dietetic interventions were recommended at baseline and reviewed at 3-month follow-up. Assessment of nutritional, functional and quality of life markers was measured using the Mini Nutritional Assessment (MNA), Timed Up and Go (TUG) and EQ-5D-5L, respectively, at baseline and after home-based dietetic intervention. RESULTS: Participants (n = 99) were recruited from consecutive referrals. Participant's weight, body mass index (BMI), total daily energy and protein intake, MNA total score, and TUG significantly improved after a 3-month nutrition intervention (effect sizes 0.257, 0.257, 0.580, 0.533, 0.577 and 0.281, respectively). The most common interventions dietitians utilised were nutrition education, use of oral nutritional supplements (ONS) and meal fortification. In total, 339 dietetic interventions were recommended to participants at baseline with 197 (58.11%) implemented at 3 months, with meal planning and referral to other relevant allied health or Commonwealth Home Support Program (CHSP) services the most implemented interventions. CONCLUSIONS: Home-based dietetic intervention improves nutritional status, functional status and quality of life in community-dwelling older adults referred for dietetic input. Improvements observed in nutritional and functional status were consistent with benchmarks of change from published literature.

OBJECTIVE: Personal protective equipment (PPE) is critical to the safety of health professionals and vital to clinical practice. However, there is little known about the cognitive and emotional impact of PPE on health professionals' performance, comfort, and well-being. METHODS: A mixed-method, cross-sectional, observational study was adopted. An online survey consisting of 5-point Likert scale questions and free-text comments canvassed the opinions of patient-facing health professionals. RESULTS: An overall negative impact of PPE on health professionals' ability to carry out work was found from 185 responses from medicine, nursing, and allied health disciplines, including increased fatigue, poor communication, and feeling uncomfortable. CONCLUSIONS: There are significant negative impacts of PPE on health professionals' ability to carry out work, impairing communication, task efficiency, and comfort. Personal protective equipment is an essential infection control practice requiring further research, design, and testing to overcome challenges.

Despite their ban and restriction under the 2001 Stockholm Convention, persistent organic pollutants (POPs) are still widespread and pervasive in the environment. Releases of these toxic and bioaccumulative chemicals are ongoing, and their contribution to population declines of marine mammals is of global concern. To safeguard their survival, it is of paramount importance to understand the effectiveness of mitigation measures. Using one of the world's largest marine mammals strandings data sets, we combine published and unpublished data to examine pollutant concentrations in 11 species that stranded along the coast of Great Britain to quantify spatiotemporal trends over three decades and identify species and regions where pollutants pose the greatest threat. We find that although levels of pollutants have decreased overall, there is significant spatial and taxonomic heterogeneity such that pollutants remain a threat to biodiversity in several species and regions. Of individuals sampled within the most recent five years (2014-2018), 48% of individuals exhibited a concentration known to exceed toxic thresholds. Notably, pollutant concentrations are highest in long-lived, apex odontocetes (e.g., killer whales (Orcinus orca), bottlenose dolphins (Tursiops truncatus), and white-beaked dolphins (Lagenorhynchus albirostris)) and were significantly higher in animals that stranded on more industrialized coastlines. At the present concentrations, POPs are likely to be significantly impacting marine mammal health. We conclude that more effective international elimination and mitigation strategies are urgently needed to address this critical issue for the global ocean health.

BACKGROUND: Interpretation bias modification (IBM) and approach bias modification (ApBM) cognitive retraining interventions can be efficacious adjunctive treatments for improving social anxiety and alcohol use problems. However, previous trials have not examined the combination of these interventions in a young, comorbid sample. OBJECTIVE: This study aims to describe the feasibility, acceptability, and preliminary efficacy of a web-based IBM+ApBM program for young adults with social anxiety and hazardous alcohol use ("Re-Train Your Brain") when delivered in conjunction with treatment as usual (TAU). METHODS: The study involved a 3-arm randomized controlled pilot trial in which treatment-seeking young adults (aged 18-30 y) with co-occurring social anxiety and hazardous alcohol use were randomized to receive (1) the "integrated" Re-Train Your Brain program, where each session included both IBM and ApBM (50:50 ratio), plus TAU (35/100, 35%); (2) the "alternating" Re-Train Your Brain program, where each session focused on IBM or ApBM in an alternating pattern, plus TAU (32/100, 32%); or (3) TAU only (33/100, 33%). Primary outcomes included feasibility and acceptability, and secondary efficacy outcomes included changes in cognitive biases, social anxiety symptoms, and alcohol use. Assessments were conducted at baseline, after the intervention period (6 weeks after baseline), and 12 weeks after baseline. RESULTS: Both Re-Train Your Brain program formats were feasible and acceptable for young adults. When coupled with TAU, both integrated and alternating programs resulted in greater self-reported improvements than TAU only in anxiety interpretation biases (at the 6-week follow-up; Cohen d=0.80 and Cohen d=0.89) and comorbid interpretation biases (at the 12-week follow-up; Cohen d=1.53 and Cohen d=1.67). In addition, the alternating group reported larger improvements over the control group in generalized social anxiety symptoms (at the 12-week follow-up; Cohen d=0.83) and alcohol cravings (at the 6-week follow-up; Cohen d=0.81). There were null effects on all other variables and no differences between the intervention groups in efficacy outcomes. CONCLUSIONS: Should these findings be replicated in a larger randomized controlled trial, Re-Train Your Brain has the potential to be a scalable, low-cost, and non-labor-intensive adjunct intervention for targeting interpretation and comorbidity biases as well as generalized anxiety and alcohol-related outcomes in the real world.

RESUMO
This study explored age, period, and cohort effects associated with trends in psychological distress and risky alcohol consumption. Data came from 108,536 Australians aged 14-79 years old from birth cohorts between 1925-2005, endorsing past year alcohol use in the 2004-2019 Australian National Drug Strategy Household Surveys. Risky alcohol consumption was split into exceeding weekly national drinking limits (>10 drinks per week) or daily limits (>4 drinks per day). An extended hierarchical age-period-cohort model was used to investigate differential effects on trends in psychological distress. Psychological distress showed an inverse U-shape throughout the lifespan with a peak in distress at age 60. Exceeding weekly alcohol limits was positively related to psychological distress prior to age 40 while exceeding daily alcohol limits remained positively related across the lifespan. There were relatively flat period effects, with no alcohol-related changes in psychological distress across years. Lastly, psychological distress gradually increased across birth cohorts until a notable spike among Australians born from 1980-2005 alongside weakening alcohol-related cohort effects. Overall, the recent increases in psychological distress did not appear to be meaningfully explained by risky alcohol consumption though risky alcohol consumption remained an important factor to consider alongside psychological distress.

Baclofen has been shown to reduce alcohol consumption in some individuals with alcohol use disorder. This preliminary study aimed to evaluate i) the effect of baclofen versus placebo on hypothalamic-pituitary-adrenocortical activity (HPA axis), as measured by cortisol, and ii) the relationship between clinical outcomes such as alcohol consumption on a randomized controlled trial of baclofen (BAC) versus placebo (PL) (Kirsten C. Morley et al., 2018; K. C. Morley, Leung, Baillie, & Haber, 2013). We hypothesized that baclofen will reduce HPA-axis activity following a mild stressor in patients with alcohol dependence. Plasma cortisol levels were taken from N = 25 alcohol-dependent patients at two time points, approximately 60 (pre-MRI scan: PreCortisol) and 180 min (post MRI scan: PostCortisol) following administration of PL, BAC 10 mg, or BAC 25 mg. Participants were followed up for the remaining 10 weeks as part of the trial for clinical outcome (percentage days abstinent). Mixed models revealed a significant main effect of medication on cortisol levels (F = 3.88, p = 0.037), no significant effect of time (F = 0.04, p = 0.84), and a significant time × medication interaction (F = 3.54, p = 0.049). Linear regression (F = 6.98, p = 0.01, R2 = 0.66) revealed that abstinence at follow-up, weighted by gender, was predicted by blunted cortisol response (ß = -0.48 p = 0.023), in addition to medication (ß = 0.73 p = 0.003). In conclusion, our preliminary data suggest that baclofen moderates HPA-axis activity, as measured by blood cortisol, and that these alterations may play a role in long-term treatment response.

INTRODUCTION: Individuals with alcohol use disorder (AUD) have difficulties regulating alcohol consumption, despite adverse drinking-related consequences. This may be due to incapacity incorporating previous negative feedback from drinking, resulting in impaired decision-making. METHODS: We assessed whether decision-making is impaired in participants with AUD related to severity of AUD, indexed by severe negative drinking consequences using the Drinkers Inventory of Consequences (DrInC) and reward and punishment sensitivity with the Behavioural Inhibition System Behavioural Activation System (BIS BAS) scales. 36 treatment-seeking alcohol-dependent participants completed the Iowa gambling task (IGT) with skin conductance responses (SCRs) measured continuously as an index of somatic autonomic arousal to evaluate impaired expectancy of negative outcomes. RESULTS: Two-thirds of the sample showed behavioural impairment during the IGT, with greater AUD severity related to worse performance. BIS moderated IGT performance according to severity of AUD, with increased anticipatory SCRs for those with fewer reported DrInC severe consequences. Participants with more DrInC severe consequences showed IGT deficits and reduced SCRs regardless of BIS scores. BAS-Reward was associated with increased anticipatory SCRs to disadvantageous deck choices among those with lower AUD severity, while SCRs did not differ related to AUD severity for reward outcomes. DISCUSSION: Effective decision-making in the IGT and adaptive somatic responses were moderated by punishment sensitivity contingent on severity of AUD in these drinkers, with impairments in expectancy to negative outcomes from risky choices, including reduced somatic responses, resulting in poor decision-making processes that may help explain impaired drinking and worse drinking-related consequences.

INTRODUCTION: Poorly designed electronic medication management systems (EMMS) or computerized physician order entry (CPOE) systems in hospital settings can result in usability issues and in turn, patient safety risks. As a safety science, human factors and safety analysis methods have potential to support the safe and usable design of EMMS. OBJECTIVE: To identify and describe human factors and safety analysis methods that have been used in the design or redesign of EMMS used in hospital settings. MATERIALS AND METHODS: A systematic review, following PRISMA guidelines, was conducted by searching online databases and relevant journals from January 2011 to May 2022. Studies were included if they described the practical application of human factors and safety analysis methods to support the design or redesign of a clinician-facing EMMS, or its components. Methods used were extracted and mapped to human centered design (HCD) activities: understanding context of use; specifying user requirements; producing design solutions; and evaluating the design. RESULTS: Twenty-one papers met the inclusion criteria. Overall, 21 human factors and safety analysis methods were used in the design or redesign of EMMS with prototyping, usability testing, participant surveys/questionnaires and interviews the most frequent. Human factors and safety analysis methods were most frequently used to evaluate the design of a system (n = 67; 56.3%). Nineteen of 21 (90%) methods used aimed to identify usability issues and/or support iterative design; only one paper utilized a safety-oriented method and one, a mental workload assessment method. DISCUSSION AND CONCLUSION: While the review identified 21 methods, EMMS design primarily utilized a subset of available methods, and rarely a method focused on safety. Given the high-risk nature of medication management in complex hospital environments, and the potential for harm due to poorly designed EMMS, there is significant potential to apply more safety-oriented human factors and safety analysis methods to support EMMS design.

Marine mammals are vulnerable to the bioaccumulation, biomagnification and lactational transfer of specific types of pollutants, such as industrial polychlorinated biphenyls (PCBs), due to their long-life spans, feeding at a high trophic level and unique fat stores that can serve as depots for these lipophilic contaminants. Currently, European countries are developing indicators for monitoring pollutants in the marine environment and assessing the state of biodiversity, requirements under both Regional Seas Conventions and European legislation. As sentinel species for marine ecosystem and human health, marine mammals can be employed to assess bioaccumulated contaminants otherwise below current analytical detection limits in water and lower trophic level marine biota. To aid the development of Regional Seas marine mammal contaminants indicators, as well as Member States obligations under descriptor 8 of the EU Marine Strategy Framework Directive, the current study aims to further develop appropriate methodological standards using data collected by the established UK marine mammal pollutant monitoring programme (1990 to 2017) to assess the trends and status of PCBs in harbour porpoises. Within this case study, temporal trends of PCB blubber concentration in juvenile harbour porpoises were analysed using multiple linear regression models and toxicity thresholds for the onset of physiological (reproductive and immunological) endpoints were applied to all sex-maturity groups. Mean PCB blubber concentrations were observed to decline in all harbour porpoise Assessment Units and OSPAR Assessment Areas in UK waters. However, a high proportion of animals were exposed to concentrations deemed to be a toxicological threat, though the relative proportion declined in most Assessment Units/Areas over the last 10 years of the assessment. Recommendations were made for improving the quality of the assessment going forward, including detailing monitoring requirements for the successful implementation of such an indicator.

Climate change is predicted to impact the distribution of many marine species. In the North-East Atlantic and elsewhere in the world, studies indicate that climate change is leading to poleward shifts in cetacean distribution. Here, strandings data collected in the British Isles from 1990 to 2020 were used to assess whether there is evidence of a shift in baleen whale distribution. Linear regression models were used to compare the number of strandings over time between six regions of the British Isles and, whilst the results indicate no significant change in the number of strandings in the most southerly region of the British Isles, there have been significant increases in more northern regions. Data related to stranded minke whales is the primary driver of these increases, with a number of potential variables affecting this trend, including observer effort. These variables are discussed and further research to explore this potential association is suggested.

AIMS: Recent studies have suggested that females respond more favourably to baclofen treatment for alcohol use disorder. Females are generally more likely to drink to regulate stress reactivity and negative affect. This study thus aimed to evaluate the role of sex on the effect of baclofen on the relationship between daily alcohol consumption, stress and craving. METHODS: A network analysis of fluctuations using vectorized autoregressive modelling was used to explore the relationship between daily surveys of alcohol consumption, stress and craving from daily diary data over 84 days from a randomised controlled trial of baclofen (30 mg or 75 mg per day) versus placebo in 104 participants with alcohol dependence (1, 2). Symptom interrelations across patients and across time were examined including temporal networks (time lagged), contemporaneous and between-subjects networks, and were examined for placebo and baclofen stratified by sex. RESULTS: Overall, between persons, there was a significant relationship between stress and drinking in placebo treated individuals in females (r = -0.70, p < 0.001) but not males (r = 0.32, p = 0.054) that was not observed in baclofen treated individuals. No relationship was observed between stress and drinking in the baclofen group for either sex (p's < 0.45). DISCUSSION: There appears to be some sex-specific differences whereby baclofen abolishes an overall association between stress and drinking in females, but this is not observed in males. Network analyses may assist in elucidating the mechanism of action of alcohol pharmacotherapies such as baclofen and understanding which symptoms and mechanisms are key for effective interventions.

PURPOSE: People with mental illness are a vulnerable and stigmatised group with poor health outcomes including greater premature mortality. This study aimed to investigate trends and rates of change in unintentional drug-related deaths for people with mental illness, describe types of medicines involved, and identify populations at risk in a cohort from New South Wales, Australia. METHODS: Features of unintentional drug-related deaths for people with mental illness between 2012 and 2016 were identified in a retrospective review of data from the National Coronial Information System. RESULTS: A total of 495 unintentional drug-related deaths were identified (1.6 deaths/100,000 population), showing an upward trend (p < 0.01). The most common substance involved was diazepam in both genders (males 135/319, 42%, female 76/176, 43%) and more than one contributory drug was included in 80% of cases. Between 2012 and 2016, amphetamine-related deaths showed the highest increase (3.2-fold), followed by codeine (2.5-fold) and quetiapine (2.5-fold). Males (RR 1.8, 95% CI 1.5-2.2) and people aged 35-44 (RR 1.7, CI 1.3-2.2) were more likely to die from unintentional drug-related deaths compared with the reference (females and people aged 25-34). CONCLUSION: This study found that the drugs commonly involved in deaths are also the drugs commonly used by and prescribed to people with mental illness. There were also significant differences between gender, age group, and marital status in the trend and rate of unintentional drug-related deaths for people with mental illness. A multifaceted approach encompassing both pharmaceutical prescribing and targeted public health messaging is required to inform intervention and prevention strategies.

AIM: Comorbid drug and alcohol and mental health disorders are highly prevalent. Significant gaps in service provision make this problem particularly difficult to address in regional Australia. The Pathways to Comorbidity Care (PCC) program was designed to improve management of comorbidity by outpatient drug and alcohol clinicians in New South Wales, Australia. This paper uses the Consolidated Framework for Implementation Research (CFIR) to evaluate variations in implementation outcomes across geographically diverse services. METHODS: Twenty clinicians across three drug and alcohol services from metropolitan, outer metropolitan and regional geographic locations were engaged at multiple levels of influence (directors, managers, clinicians) during the implementation of the multimodal PCC training package. The CFIR guided the development of self-report measures and semi-structured interviews evaluating implementation of the PCC training, and disparities in implementation barriers and facilitators were determined. RESULTS: Metropolitan clinicians identified less barriers than regional clinicians on several intervention characteristics (adaptability, complexity, design quality and packaging), as well as outer setting (peer pressure), inner setting (implementation climate, staff incentives, leadership engagement, available resources) and process (planning, opinion leaders, executing) domains. Regional clinicians evaluated the networks and communications construct more favourably. CONCLUSIONS: Specific barriers identified more strongly by regional clinicians included the importance of communication with local clinicians and leadership about the practicalities of incorporating the approach into routine practice (allocation of time, increased accessibility of implementation team). Metropolitan clinicians provided more favourable evaluations of the package design, implementation climate and specific implementation processes such as a clear and informative implementation plan.
